A murder and a missing person case puts McAvoy on the track of a man whose desire for revenge is unstoppable - but who may not be the worst criminal involved.
The police think Crystal Heathers isn't missing.
The trainee detective assigned to the case isn't so sure.
McAvoy thinks someone was being held at the derelict building where they just found a body pinned to the wall...and that all the signs point to it being a little girl.
But why would anyone not report a kidnapping?
And how far would someone go to get revenge?
The case will test McAvoy to breaking point - as the crimes of the present lead him to a final violent confrontation with an enemy from his own past.
David spent more than fifteen years as a journalist, including seven years as a crime reporter with the Yorkshire Post - walking the Hull streets that would later become the setting for the Detective Sergeant Aector McAvoy novels.
